In a row of letters, a letter is 4th from left end and 13th from the right end. How many letters are there in the row?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 16
Counting from the left and counting from the right both include the given letter, so adding the two positions counts it twice. The number of letters is therefore \(4+13-1=16\).
